Improvement in arm-revolving shelves



PATENT CFFICE.

PHILIPP NICHOLS, OF TROY, NEW YORK.

IMPROVEMENTV IN ARM-REVOLVING SHELVES.

Specification forming part of Letters Patent No. 117,103, dated July 18,1871.

To all whom 'it may concern:

Be it known that 1, PHILIPP NICHOLS, of the city of Troy, in the coiuityof Rensselaer and State of New York, have invented Arm-RevolvingSupportShelves, of which the followingis a specification My inventionrelates to a device by which, for convenience or use, a shelf' orshelves may be readily adjusted to column, pipe, or post, and removed,as occasion may require, without injury to the vertical support, while,by means of the revolving or friction-bearing arms, the relativeposition of the shelves may be changed, the shelves held firmly near toor remote from each other so as to give a greater or lessershelf-surface, as occasion may require, and, as constructed andarranged, in operation greatly subserves economy in space, and, withcomparatively little expense, prove of varied application.

Figurel is a horizontal view of my device.

Fig. L). is a vertical sectional view of the same,

showing particularly the openings in which the connecting-bolts pass insecuring the arms to the collar. Fig. 3 is perspective view of thedevice secured to a post or pipe with a pendent hook attached to theshelf. Fig. 4 is a horizontal view similar to Fig. 1, showing diiferentforms of shelf.

Fig. 5 is a perspective view of the collar, showing it open. Fig. 6 is aview perspective of the same closed and in reversed position. A is thecollar, Ywhich is joined by mutuallysupporting hinge or joint at C. At Ois shown the point of contact of the spurs or lips of the collar. Al Aare flanges extendingoutwardly from the collar sufficiently far tosupport the inner extremity of the arm. B is the arm, which is securedby a bolt to the ilange A. B B are shelves on the outer extremities ofthe lateral arms. D represents a pillar, post, or pipe, around which thecollar of the device is clasped; h, a hook pendent from the shelf. Thedevice may be made of wood, with iron nuts and bolts for fastenings,though I prefer to make the different parts of the device of iron orother metal, with sufcient thickness, width, and strength to sufce forits different applications.

The collar A should be made of such width and thickness as theparticular use may require, and of such form as to be readily and rmlyclasped to its vertical support. The inner eX- tremity of the arm B isrounded, so that, when 1' turned from side to side, it may pressstrongly against the outer circumference of the collar, and a bolt inthe opening made in the ila-nge A, and through the arm above, holds samefirmly in position. At C and O the corresponding extremities mutuallysupport each other.

In operation the collar is opened by unscrewing the nut at Gf. Thecollar is then clasped around the pillar or pipe-support at any requiredheight, and the arms are moved near to or remote from each other, asgreater or lesser shelfsurfacc is needed.

The shelves may be of any required shape, diii'erent forms of which areshown in Fig. 4, also different positions of the shelves are indicatedin Figs. 1 and 4 by heavy and dotted lines.

As will be seen, the device may be readily clasped upon pillars inwarehouse to sustain or show goods in the center of room or away fromthe sides; upon stove-pipes to hold and warm vessels; upon posts arounddwellings for domestic purposes, and for various uses as the eXigencymay require. The relative positions of the shelves may be changed, whilehooks pendent from the same may be drawn together or thrust apart, asthe case may require, in suspending clothing or other anticles thereon;and the device in its varied uses subserves greater economy andconvenience in space, more ready capability of changing shelf-surface,and less expense in adaptation to its varied applications than shelvesheretofore used.

I claim- The combination and arrangement of two or more rotating orrevolving shelf-arms upon the same plane, and resting upon and supportedby corresponding flanged supports A A A cast or constructed with thepipe-collar lor clasp, when arranged as described and set forth.

PHILIBP NICHOLS.
